UNITED STATES PATENT OFFICE.

FRANKLIN C. NICKEL, OF CONCORD, ILLINOIS, ASSIGNOR TO MONMOUTH ACETYLENE- ELECTRIC MANUFACTURING COMPANY, OF MONMOUTH, ILLINOIS, A CORPORATION OF ILLINOIS.

ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Oct. 20, 1908.

To all whom it may concern:

Be it known that I, FRANKLIN O. NICKEL, a citizen of the United States, residing at Concord, in the county of Morgan and State of Illinois, have invented a new and useful Improvement in Acetylene-Gas Generators, of which the following is a specification.

My invention relates to an improvement in the class of gasometenappar'atus for generating gas from calcium-carbid by feeding the latter automatically to the water-containing generating-chamber of the apparatus. Such a generator forms the subject of Letters Patent No. 795,478, dated July 25, 1905.

The primary object of my inventionis to provide novel and effective means for automatically taking care of the condensation from the generated gas in the apparatus and of the pressure and volume relief of the apparatus.

In the accompanying drawing, Figure 1 is a View in vertical sectional elevation of an acetylene-gas generator containing my im provements, and Fig. 2, a broken section on line 2, Fig. 1.

The apparatus shown to be provided with my improvements involves, as its general construction, that illustrated and described in the aforesaid patent, though it is not intended to limit my present invention thereto.

The reservoir 3 for containing the sealing water, the level of which is indicated at '1, is provided in its lower part with a crownlike false bottom 5 forming in the base portion of the reservoir the generating chamber 6 containing water, the level of which is indicated at 7. The outlet-pipe 8 for the generated gas rises from the generating chamber, and the gas-discharge pipe 9 extends parallel therewith to receive into its upper end the gas which flows from the corresponding end of the pipe 8 into the gas-space in the upper part of the gasometer-forming bell 10, which works in the reservoir 3 in a usual manner. The pipe 9 has coupled to its lower end an extension 9 projecting at a right-angle from it through the wall of the reservoir, beyond which there rises from its end a pipe 11, which passes centrally through the purifier 12 consisting of a closed cylinder filled with cotton-felt 13, or other suitable purifying medium.

The pipe in the purifier contains perforations at 14 in its lower end and similar perforations 15' in its upper end, with a plug 16 between its ends to direct the gas from the pipe 9 by way of perforations 14 through the medium 13 and effect therein its purification and return the purified gas through the perforations 15 into the pipe 11, which connects beyond the upper end of the purifier with the service-pipe 17 at a shut-off valve 18.

The means provided for automatically supplying the calcium-carbid in proper pro-, portions to the generator 6 may be the same as are illustrated and described in the aforesaid patent and need not, therefore, be shown in all details in the present drawing, which presents thereof, by way of identification, only the tubular member 19 communicating at its lower end through the false bottom 5 with the generating chamber, the inverted cup-like member 20, the U-shaped vertically movable bar 21, one upper end of which (not shown) is connected with the device for controlling the feed of calcium-carbid from its container (also not shown) into the member 19, and its other upper end in engagement with a lever 22 having one end fulcrumed at 23 and its opposite end linked to the top of the bell 10.

The parts thus far described present no important features of novelty.

At one side of the generating-chamber 6 is supporting on its wall an external condensation-chamber 24: extending upwardly beyond the water-level 7 and provided thereat with an overflow 24 the top of this chamber be ing open to permit free access to itfor clean ing and otherpurposes. A relatlvely narrower extension 25 of the condensation chamber 24, freely communicating therewith through an opening 26 in the wall of the generating-chamber and affording a supplemental condensation-chamber, is supported on the inner side of said wall to reach upwardly to the water-level at 7. A branchpipe 27 depends from the extension 9 into the chamber 24. to take from the purifier 12 the water of condensation that accumulates in the latter and which, if left therein, would tend to impair the gas; and any water of condensation in the pipe 9 also drains off through the branch 27. A blow-01f pipe 28 extends vertically in the bell 10, passing. through its upper closed end to discharge to a the atmosphere and extending at its lower end through the false bottom 5, below which it terminates in the chamber-section 25 in an expanded tubular head 29 serrated to afford opening-producing teeth 30 about its open lower end. A branch 31 of the escape-pipe 28 communicates therewith above the false bottom and rises to extend parallel with the pipes 8 and 9 in a guide-sleeve 32 depending centrally in the bell 10 and containing at a proper height above its open lower end, perforations 33.

The gas generated from calcium-carbid fed into the water contained in the chamber 6, as in the manner set forth in said patent, and which accumulates in the space above the water-level 7 finds its outlet through the pipe 8 into the space above the water-level in the gasometer 10, which is supported, as usual, by the pressure of the gas in it, to produce by its weight the pressure for the service. From the gasometer the gas discharges through the pipe 9 to the service pipe 17 through the purifier 12, whence the water of condensation discharges into the chamber 2st. In the event of the apparatus generating an excess in volume of the gas, when the resultant accumulation in the gasometer raises the bell 1O suificiently to elevate the perforations 33 in the guide-sleeve 32 above the water-level at 4, the surplus gas will have access to those perforations and pass into the upper end of the pipe 31 to be carried by it to the blow-off pipe 28, which conducts it to the atmosphere. In the event of the apparatus generating an excessive pressure of gas in the chamber 6 the excess of pressure, acting against the surface of the water in that chamber, will lower its level in the chamber 25 to the serrations 30, the overflow 2& taking care of the excess of water thereby introduced into the chamber 24; and because the depression of the level in the chamber-section 25 opens communication, at the serrations 30, between the generatingchamber and the interior of the head 29, the excess of pressure will be relieved through the pipe 28 to escape into the atmosphere. All accumulation of water of condensation in the pipes 28 and 31, which would tend to obstruct those pipes, is prevented by their draining into the condensation-chamber.
